IP Address (CIDR Support)：

CIDR (Classless Inter-Domain Routing) is designed for advanced use cases, such as servers, cloud environments, or multiple machines sharing a range of IP addresses.

CIDR defines an IP range using a network address followed by a slash and a prefix length (for example, 192.168.1.0/24). Only API requests originating within the specified CIDR range will be accepted.

The slash (/) number controls how many IP addresses are included:

• Larger numbers (such as /32) allow fewer IPs and are more secure.

• Smaller numbers (such as /24 or /16) allow more IPs and create a wider access range.
